l N C U BAT O R SPECIFICATION forming part of Letters Patent No. 511,546, dated December 26, 1893.v

Application filed February 13, 1893. Serial Fo. 462,135. (No model.)

To all whom it may concern:

Be it known that I, CHARLEY DELLNO PUR- VIS, a citizen of the United States, residing at Oardington, in the county of Morrow and State of Ohio, have invented certain new and useful Improvements in Incnbators; and I do declare the following to be a full, clear, and exact description of the invention, .such as will enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a partot' this specification.

The special object of the invention is to make an incubator in which the proper degree of temperature may be easily maintained; the eggs conveniently turned at the proper times; the chickens as they hatch separated from the unhatched eggs; and the moisture pans removed without disturbing the eggs.

Figure l of the drawings is a longitudinal vertical section on dotted line w :n of Fig. 2; Fig. 2 a vertical cross-section on the dotted line y y of Fig. 1, and Fig. 3 a detail plan view of the covered pan at the top of incubator; Fig.

4 a perspective view of the egg turner; Fig.

5 a similar View of the egg-support formed of two interlacing and separable frames, and Fig. 6 a similar view ofthe Water pans in their sliding holder. Y

In the drawings, A represents the casing of the incubator with a projection a in which is placed a lamp B or a heater of any suitable kind. Over this is placed a boiler C concaved on the under sideto form a combustion chamber communicating with a smokepipe b, the Water chamber being thus made to surround the heater, while the latter receives a supply of air through the bottom from holes in the bottom or near the bottom of the projection a.

D is the covered pan into which water is poured so as to pass through bottom holes d into the boiler or Water jacket C until the pan and water jacket are both full or nearly so, the top of pan being a little above that of the jacket, the Water being at the same height or nearly so. kAs the Water becomesheated, the Warm water pushes its Way up through the channel E into the pan While the cooler water passes down through the holes d, thus producing a continuous circulation ot' hot water from which the inside of the incubator may be kept at the desired degree of temperature. I may use del'lectors F to direct the course of the water in the pan D.

D is the pan cover lwhich lits closely into the upper part of the pan and is provided with the vertical pipe d on Which is a screw cap d2. The pan D is supported upon the opposite ribs 0,2 d2 so as to be easily put in and taken out, and beneath it is placed the frame K which has the handles k2 k2 and the partitions la la* to form spaces within which each egg shall be placed to itself, the eggs bearing lightly against said partitions and being supported by the strips g of the frame G. The frame G has projections g that slide on or off the side-pieces h h of the frame H from which it may thus be easily separated.

Below the frames G H are arranged the moisture pans I in a slide J so that the Water in the pans may be replenished without disturbing the eggs. Below the moisture-pan slide is arranged a mattress or equivalent receptacle for the chicks as soon as they are hatched and to which they drop. In about twenty days hen eggs may begin to hatch, when the frame G and slide J are removed to permit the chicks to drop through the spaces between the strips of frame H.

It will be observed that the Slat-frames G H are so connected that the frame G may be adjusted in one direction to regulate the spaces between the slats and slides and also at right angles thereto so as to be taken away from frame H.

What Iclaim as new, and desire to protect by Letters Patent, is

l. In an incubator, the frame H, formed of longitudinal slats connected at the ends by cross-slats h h, in combination with the frame G l having longitudinal slats connected by crossslats to leave projecting ends g g adapted to slide on the cross slats h h both longihatehedyonng permitted to fall upon a soft tudinally and transversely as and for the purreceptacle as set forth.

poses set forth. In testimony whereof I affix my signature in 2. In an incubator, the combination with a presence of two witnesses. 5 separable slatted egg support, of a subjacent @HARLEY DELLNO PURVIS.

removable slide containing the Water pans and Witnesses: below this a mattress; whereby the slide and H. BOWEN,

part of egg support may be removed and the O. P. RUSSELL.
